POTENTIAL SOURCES OF POLLUTION
Managing and Improving Water Quality

• Providers
• Fuel and oil storage/disposal
• Sanitary/domestic effluent discharges
• Wash down water anti-fouling debris waste
  disposal
• Diffuse pollution surface water run-off
• Maintenance Dredging
• Marina Building Development
• Buildings Maintenance Hot Cold water systems
  Legionella

• Users
• Sanitary waste water
• Grey water detergents (washing up water etc)
• Discharge of chemicals via bilge water or leaks
• Accidental spillage of fuels
• Boat Wash down
• Use of antifouling substances
• Use of Paints/solvents
• Stored water Legionella Control

• Outside Sources
• Point source discharges upstream river
  pollution
• Diffuse pollution

IMPLICATIONS IF WATER QUALITY IS NOT MANAGED
Managing and Improving Water Quality

• Aesthetic damage
• Public health risk
• Environment
• Legal
• Detrimental effect to others
• How do we prevent these problems?

WATER QUALITY MONITORING SHOULD PROVIDE DATA TO
Managing and Improving Water Quality

• Demonstrate compliance with legislation
• Show control measures work
• Demonstrate best practice is in place
• Ensure Public Health protection
• Support Environmental Impact Assessment/Baseline
  studies
• Investigate pollution sources
• Prove that pollution may be due to sources
  outside of the marina
• Enhance company reputation

KEY WATER QUALITY INDICATORS
Managing and Improving Water Quality

• Monitoring needs to be tailored to the
  activities, risks and environment. Data should
  be interpreted to relevant legislation and
  standards for example
• Bacteria levels assessed with respect to EU
  Bathing Water Directive standards
• Effluent quality assessed against IPPC
  Discharge Consents
• PHYSICO-CHEMICAL
• CHEMICAL
• BIOLOGICAL

WHATS IN YOUR WATER?
Managing and Improving Water Quality

• Microbiological spot samples collected

• Test results
• Water quality variations

EXAMPLES OF CURRENT PROJECTS AND INITIATIVES
Managing and Improving Water Quality

• EMU LTD
• Dover Harbour Board Ongoing WQ programme - EMS
• Southampton Container Terminals discharge
  consents
• Chichester Harbour Conservancy bacteriological
  testing
• Southampton Activities Centre bacteriological
  testing
• MDL Marinas Testing of water quality for
  wash-down treatment system
• OTHER INITIATIVES

CONCLUSIONS
Managing and Improving Water Quality

• Water - a primary asset
• Manage and control this asset
• Data is essential
• Publish and use data
• Routine monitoring neednt be costly
